Answer
$B\cup(A\cap C)=\{2,5,11,17,1, 4, 9, 16\}$
Work Step by Step
The union of sets is the set of elements that are in at least one of the sets.
The intersection of sets is the set of elements that are in all of the sets. The complement of a set is the set of elements that are not in the set.
Hence here $B\cup(A\cap C)=\{2,5,11,17,1, 4, 9, 16\}$
